1. Create database and run script

set term ^;

create or alter view v1
as
  select 1 as n from rdb$database
^

create or alter function f1
  returns integer
as
declare ret integer;
begin
  select n from v1 into ret;
  return ret;
end
^

create or alter procedure p1
  returns (ret integer)
as
begin
  select n from v1 into ret;
end
^

set term ;^

2. Check dependencies:

SQL> show function;
Global functions

Function Name Invalid Dependency, Type
================================= ======= =====================================
F1 V1, View

SQL> show procedure;
Global procedures

Procedure Name Invalid Dependency, Type
================================= ======= =====================================
P1 V1, View

Result: dependencies is OK

3. backup database and restore backup into new database (using gbak)

4. connect to the restored database and check dependencies

SQL> show function;
Global functions

Function Name Invalid Dependency, Type
================================= ======= =====================================
F1 RDB$PAGES, Table

SQL> show procedure;
Global procedures

Procedure Name Invalid Dependency, Type
================================= ======= =====================================
P1 V1, View

Result: dependencies of function F1 is wrong, while dependencies of procedure P1 is OK
